Data release for Geochemical evidence for the origin of late Quaternary loess, Seward Peninsula, Alaska Data release for Geochemical evidence for the origin of late Quaternary loess, Seward Peninsula, Alaska
Loess is the most widespread surficial deposit in the state of Alaska. Although loess of last-glacial age is common in mid-continental North America, records of last-glacial loess in Alaska have been elusive. Here we report a record of last-glacial loess on the Seward Peninsula, along with studies of a transect of loess localities also thought to date to the last glacial period. Highly...
Effects of restoration treatments at the piñon-juniper/ponderosa pine in northern New Mexico Effects of restoration treatments at the piñon-juniper/ponderosa pine in northern New Mexico
This dataset includes multiple data types from long-term monitoring and research on Rowe Mesa, NM, including data on surface fuels, ground cover, overstory tree metrics, regeneration, and tree-ring widths before and after burning and thinning treatments from 2005-2024. This data release includes 8 CSV files: DBH_DSH_conversion_data.csv (data used to create a regression of tree diameters...
Updated Estimates of Water Budget Components for the Mississippi Embayment Region Using a Soil-Water-Balance Model, 2000–2024 Updated Estimates of Water Budget Components for the Mississippi Embayment Region Using a Soil-Water-Balance Model, 2000–2024
This item provides Soil-Water-Balance (SWB) model input and output of a water budget simulation for the Mississippi Embayment Regional Aquifer System (MERAS) during the period 2000 to 2024. The output files include gridded daily data (1-kilometer resolution) for net infiltration (potential groundwater recharge), rejected net infiltration, interception, runoff, runoff outside (runoff that...
High-Resolution Imagery of the McKenzie River, Oregon, 2022 and 2023 High-Resolution Imagery of the McKenzie River, Oregon, 2022 and 2023
The U.S. Geological Survey (USGS) developed high-resolution orthomosaics from natural color aerial photographs collected by the Civil Air Patrol (CAP) of the McKenzie River in the Willamette River Basin in Oregon in 2022 and 2023. Aerial photographs were collected between September 20 and September 24, 2022, and again between July 1 and July 3, from a Cessna 182 aircraft with a Waldo Air...
High-Resolution Imagery of the North Santiam River, Oregon, 2022 and 2023 High-Resolution Imagery of the North Santiam River, Oregon, 2022 and 2023
The U.S. Geological Survey (USGS) developed high-resolution orthomosaics from natural color aerial photographs collected by the Civil Air Patrol (CAP) of 45-60 km of the North Santiam River in the Willamette River Basin in Oregon in 2022 and 2023. Aerial photographs were collected between September 14 and September 22, 2022, from Detroit Lake to Stayton, and again between July 7 and July...
Northern mockingbird ileal virome variation in Texas (ver. 2.0, January 2026) Northern mockingbird ileal virome variation in Texas (ver. 2.0, January 2026)
A few studies have focused on avian gut virome variation in response to environmental stressors, but none have assessed virome in relation to chemically intensive crops, the production of which effects various aspects of avian health and fitness, and deleteriously alters available food resources. In this study we used shotgun metatranscriptomics (2 x 150bp; Illumina HiSeq 4000 with...
